4-Quadrant analog multiplier in 8-SOIC
The AD834JRZ: The 4-quadrant topology means the output is the linear product of two input signals regardless of polarity — the transfer function holds through all four sign combinations, so it handles AC-coupled waveforms and bipolar modulation without external level-shifting. The 8-SOIC footprint (3.90 mm body width) matches the standard SOIC-8 land pattern — no special pad geometry or thermal vias required for this device. The listed supplier device package is 8-SOIC, confirming the same mechanical outline as the package/case entry.
Analog Devices lists the AD834JRZ lifecycle status as active. The part is RoHS3 compliant, meeting the latest EU restriction-of-hazardous-substances directive without exemption.
